I recently moved my gear out of my house into a commercial space and need to have it insured. My insurance broker has had trouble finding and insurance company willing to insure a "audio post house", "recording studio" or "video production facility"

The one company that was willing to insure said they will not cover software licenses. Between my ilok and other dongles i have quite an investment in licenses and if they disappear or are damaged for some other reason I guess i would be SOL. Anyone have a better suggestion or insurance solution?

For my gear (mostly location sound) there are several film industry specific companies that insure movie equipment specifically. I would think post house equipment would be covered as well, iLok stuff should be specified tho, I'm not sure about that.

Just got a post card from the "Film Emporium" It says they offer insurance to film makers. You might want to try them. Their website is https://www.filmemporium.com/ but when I tried to access it I got a warning saying the site was untrusted. FWIW

You can insure software (iLok even offers their own) and I have, for decades.
There are some app makers who warn you about insuring your software dongles just like a piece of equipment, for this reason.

I don't quite understand why you need insurance for software, because that's not what you want to insure, but I think it will be useful for you to read this post here. That's more about insurance software, but I'm sure through this article you can find some sites or companies which could help you. Well, if this article doesn't help you, you can read some more or write a letter to the author and ask about the insurance company they use for their software.
